Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577634, here are decompositions:

41 + 31577593 = 31577634
43 + 31577591 = 31577634
47 + 31577587 = 31577634
103 + 31577531 = 31577634
107 + 31577527 = 31577634
113 + 31577521 = 31577634
163 + 31577471 = 31577634
233 + 31577401 = 31577634

Showing the first eight; more decompositions exist.
